Conference video: Assembly and Manipulation of Molecules at the Atomic Scale

At the 2013 Conference the winner of the 2011 Feynman Prize for Experimental work presents STM studies showing how the manipulation of single molecules on a surface can yield insights to their mechanical, electronic, and optical properties, and be used in a controlled way to build pre-defined molecular architectures.

Germanane: germanium&#39s answer to graphane

Soon after graphene sheets were being produced on a laboratory scale routinely, researchers began producing the hydrogenated version graphane (with a hydrogen atom on each carbon). This step is one of many approaches aimed at harnessing graphene’s powerful conductivity and is also being explored for hydrogen storage and other potential applications (more info in this… Continue reading Germanane: germanium&#39s answer to graphane

Proposed Brain Activity Map may also advance nanotechnology

A proposed large project to produce a dynamic map of the functional connectome of the human brain will require a convergence of neuroscience, biotechnology, nanotechnology, and computation, and may therefore spur the development of advanced nanotechnology leading to molecular manufacturing.

The potentially world-changing research that no one knows about

Too much reliance on opportunity-based research could significantly hinder scientific advancement. We have the ability now to explore the specifics of potential future technologies, and the knowledge gained could, in turn, add useful and possibly surprising priorities for research today.

Measuring individual chemical bonds with noncontact-AFM

Noncontact atomic force microscopy using a tip functionalized with a single molecule provides highly precise measurement of individual chemical bond lengths and bond orders (roughly, bond strength).

Nanotechnology, DNA sequencing, and personalized medicine

Artist’s conception of a nanopore drilled into a layer of graphene to speed up DNA sequencing. One of the greatest promises of near-term nanotechnoloogy is cheaper DNA sequencing to speed the development of personalized medicine. There are not only genetic differences between different patients, but also genetic differences between, for example, different cancers of the… Continue reading Nanotechnology, DNA sequencing, and personalized medicine

Nanotechnology using designed peptides to build supramolecular structures on surfaces

An algorithm helps design peptides that will self-assemble on a given surface to produce a supramolecular structure of desired geometry.

Nanotechnology leading toward spin computers

Inserting a nanometer-thick insulating layer on graphene enables spin injection into graphene, a step toward spin computers.

Single-atom sheet of carbon clears arsenic from water

We can get a hint of the power coming from longer-term nanotech by seeing what is being discovered today on how to use some of the new materials becoming available.  Many of us have been intrigued with graphene, a one-atom-thick planar sheet of bonded carbon atoms.  It’s no surprise that exciting applications are being found… Continue reading Single-atom sheet of carbon clears arsenic from water

Steam balloons

The brothers Montgolfier invented the hot air balloon upon the observation that smoke rises, and thus they figured that if they could catch it in a bag, the bag would be pulled upward. Hot air ballooning is quite popular today; people think of balloons as being quaint and pretty and natural, or at least more… Continue reading Steam balloons
